| =e re Project 22,3 - S-nit Monitoring - C. E, Ingersoll E, C. Woodward The technique used for monitoring the Samit consisted of telemetering . sigrzls from signal scurces in the ismediete netrhberheet of ~~’ (Mohavk) device by high frequency radiofrequency estho!s to a receiving and recording station locate’ on Parry. The aignals vere then recorded on oscillographs. The signal sources were the load rirg pulse of the I-unit and the output of a fluor-photemultiplier ‘etector near the S-unit vhich seasured both ‘he S-unit output and the gasma rays from the ruclear reaction. The oscillograph d4ieplays consisted of s raster scope iisplay containing al] signals and a linear sveep “ispley on a 517 cecillograph whieh shoved greeter detail of the load ring pulse signal ani the S-unit signal. The resulte of the measurement are as follows: Tine from beginning of X~unit load ring pulee te beginning of firet S-unit palse = Yield of first S-unit Time from beginning of Y~unit load ring pulse to beginning of Beoond S-unit pulse Yield of second Seunit Time from berinning of Y-unit load ring pulse to beginning of ————r rieit of taint soit~ a Time from beginning of S-unit load ring pulse to treekavay of coe | Ot a pest AVAILABLE © ~ ~” coPY a gamma pulse rise = C7
